This gist has a bigger example of what I'm trying to do, but just
understanding how to make the following short example work, and/or why
it doesn't, will probably get me through the bigger problem.
testit.rb:
require 'pp'
class A
@@a = [7]
def self.get_a
@@a
end
def self.put_a
pp @@a
end
end
class B < A
@@a = A.get_a.dup
@@a = [8]
def self.put_a
pp @@a
end
end
A.put_a
B.put_a
A.put_a
[wwalker@dogwood inherit_settings] $ ruby testit.rb
[8]
[8]
[8]
I would expect:
[7]
[8]
[7]
I don't see my error. I think that maybe dup() doesn't work on a class
variable, or that maybe class variables are not really class variables,
but are rather hierarchy variables that can only exist in one place in
an class and it ancestry?
